This article mainly introduces which is good to use, a cloud server or an ordinary server. What is the difference, has a certain reference value, friends in need can refer to. Let's take a look at it with me.

1. Different flexible allocation of resources

CVM supports flexible provisioning of resources, which means that we are free to increase or decrease CPU, memory, disk, bandwidth and other resources. However, we should also be aware that this kind of auto scaling includes not only vertical scaling in a single CVM, but also horizontal scaling in increasing / reducing the number of virtual machines.

Ordinary server resources are limited by the configuration of a single server. If resource expansion is needed, technicians are required to add disks or memory strips to the physical server hardware. The time cost of this process is difficult to support the flexible changes of enterprise application requirements.

2. The node size is different.

The computing resources of cloud servers are scheduled from a large number of physical servers that have been consolidated and virtualized. In terms of node size, the virtualization scale may be several, dozens or hundreds of physical servers. It may also be thousands of physical hardware across the data center to build a large cloud virtual resource pool.

The node size of ordinary servers is limited by the hardware environment such as cabinets and computer rooms, as well as the degree of virtualization.

3. Distributed storage is different.

CVM uses distributed storage, such as ceph distributed storage system adopted by Zhiyun, which is characterized by good scalability, high performance and high reliability. It can achieve real-time multi-copy disaster recovery, no single point of failure, effectively avoid a variety of failures, support the elastic scaling of storage resources, and enable CVM to have functions such as hot migration.

Ordinary servers can not achieve distributed storage, in the event of hardware failure, data security will face serious risks such as loss, damage or even unable to retrieve, so enterprises usually deploy RAID10 array security strategy, but this requires high hardware purchase and other costs and costs, increasing the financial burden of the company.

4. Different concepts

Cloud server is a concept from WEB3.0, which has the characteristics of highly distributed and highly virtualized. The common Qingniu Business opportunity Intelligent Marketing Cloud Terminal is the world's first lightweight desktop-based communication and information management marketing platform.

An ordinary server, also known as a server, is a device that provides computing services. Because the server needs to respond to the service request and process it, generally speaking, the server should have the ability to undertake and guarantee the service.

The composition of the server includes processor, hard disk, memory, system bus and so on, which is similar to the general computer architecture, but because of the need to provide high and reliable services, therefore, it requires high processing capacity, stability, reliability, security, scalability, manageability and so on. In the network environment, according to the different types of services provided by the server, it can be divided into file server, database server, application server, WEB server and so on.

As a senior professional cloud computing service provider and cloud security service provider in the industry, it is committed to providing cloud servers for Internet enterprise users and enterprise users in traditional industries. Its products have the characteristics and advantages of "security and stability, easy to use, high service availability, high performance-to-price ratio" and are designed to be customized for enterprises to meet the needs of rich and diversified application scenarios.
